Priests, cardinals, archbishops and bishops will lead the official installation of Buffalo's new Roman Catholic bishop.

The installation Mass for Bishop Richard Malone is scheduled for this afternoon at St. Joseph Cathedral in Buffalo.

The 66-year-old Malone spent eight years as bishop in Portland, Maine. Pope Benedict XVI selected him in May to succeed retiring Buffalo Bishop Edward Kmiec.

Malone will serve as apostolic administrator for the diocese while the Vatican searches for a new bishop there. A representative with Diocese of Portland says it could take up to a year for a new bishop to be appointed to Maine.
